HRESULT get_Area3D(
double* Area
);
[C++]Parameters
Area [out, retval] Area is a parameter of type double
Product Availability

Remarks
If Patches comprising a MultiPatch geometry have improperly ordered vertices such that positive faces are not pointing outwards, a negative 3D surface area will be returned. To ensure proper orientation, add vertices in a clockwise manner relative to an observer situated outside of the MultiPatch geometry.
